Check pool math. Be careful with that if you are premixing it in a bucket it can actually burn your hand.
According to PoolMath, I need to add in 12 pounds (pool is 10,000 gallons).
I realize that my original question was worded rather vaguely, as my concern was in regards to there being a limit as to how many pounds of CH one can add to a pool in a given application.

I would suggest doing it in stages. As PoolGate said, you can only dissolve 1 or 2 pounds in a 5 gallon bucket of water at a time or it will get dangerously hot. So maybe do 4 pounds a day, with a day in between. Be sure you are not adding any other chemical (except chlorine) when adding the calcium.
Odd that you need to add calcium to a pool in Texas. Most of the reports we see from Texas has hard water.

Our city water has less than four (4) ppm of calcium out of the tap, so anytime you backwash or vacuum to waste, out comes the bucket of calcium chloride (it also has a TA of 320, but that's a headache for another thread).

Are you sure about that low LOW CH reading? I thought *my* CH was about as low as city/county water got at 40ppm????

Yep, I never could get any reading whatsoever with my Taylor test kit, so decided to check with the City, and sure enough, their most recent annual water quality report showed a calcium level of 3.49 PPM.Are you sure about that low LOW CH reading?

To look at it on the bright side, at least we don't have to worry about kidney stones around here.
In Texas our tap water has 0 hardness so during the summer when you get no rain you need to add calcium about every week to keep up with the water line replenisher. Rain water has more calcium than public water (0 calc). Houston area.

Nope, no limit.
I broadcast the calcium on the top of the pool water. Use a scoop and toss it on the water. It dissolves easily. If it does settle into the bottom of the pool then brush it around.
I added a 25lb bag of Snow Joe calcium chloride delivered from HD that way.
Watch your FC after adding calcium. There are reports of calcium addition causing FC to drop.

+1 - I just broadcast it off the end of the diving board. I do not pre-mix in a bucket the water gets too hot.
